Mikhail Moiseyevich Botvinnik

Mikhail Moiseyevich Botvinnik, PhD (August 17 [O.S. August 4] 1911 – May 5, 1995) was a Soviet and Russian International Grandmaster and three-time World Chess Champion. Working as an electrical engineer and computer scientist at the same time, he was one of the very few famous chess players who achieved distinction in another career while playing top-class competitive chess. He was also a pioneer of computer chess.Botvinnik was the first world-class player to develop within the Soviet Union (Alekhine was a top player before the Russian Revolution), putting him under political pressure but also giving him considerable influence within Soviet chess. From time to time he was accused of using that influence to his own advantage, but the evidence is unclear and some suggest he resisted attempts by Soviet officials to intimidate some of his rivals.
